我非常喜欢命令行解析器库(http://commandline.codeplex.com/)。它有一个非常简单和优雅的方式来通过属性设置参数:

class Options
{
    [Option("i", "input", Required = true, HelpText = "Input file to read.")]
    public string InputFile { get; set; }

    [Option(null, "length", HelpText = "The maximum number of bytes to process.")]
    public int MaximumLenght { get; set; }

    [Option("v", null, HelpText = "Print details during execution.")]
    public bool Verbose { get; set; }

    [HelpOption(HelpText = "Display this help screen.")]
    public string GetUsage()
    {
        var usage = new StringBuilder();
        usage.AppendLine("Quickstart Application 1.0");
        usage.AppendLine("Read user manual for usage instructions...");
        return usage.ToString();
    }
}

请使用apache commons cli API的。net端口。这很有效。

http://sourceforge.net/projects/dotnetcli/

以及用于概念和介绍的原始API

http://commons.apache.org/cli/

Powershell Commandlets。

powershell根据命令行中指定的属性进行解析，支持验证、参数集、流水线、错误报告、帮助，最好的是返回。net对象供其他命令行使用。

这是我基于Novell Options类编写的处理程序。

它针对的是执行while (input !="exit")样式循环的控制台应用程序，例如一个交互式控制台，例如FTP控制台。

使用示例:

static void Main(string[] args)
{
    // Setup
    CommandHandler handler = new CommandHandler();
    CommandOptions options = new CommandOptions();

    // Add some commands. Use the v syntax for passing arguments
    options.Add("show", handler.Show)
        .Add("connect", v => handler.Connect(v))
        .Add("dir", handler.Dir);

    // Read lines
    System.Console.Write(">");
    string input = System.Console.ReadLine();

    while (input != "quit" && input != "exit")
    {
        if (input == "cls" || input == "clear")
        {
            System.Console.Clear();
        }
        else
        {
            if (!string.IsNullOrEmpty(input))
            {
                if (options.Parse(input))
                {
                    System.Console.WriteLine(handler.OutputMessage);
                }
                else
                {
                    System.Console.WriteLine("I didn't understand that command");
                }

            }

        }

        System.Console.Write(">");
        input = System.Console.ReadLine();
    }
}
